Tinplate sheet printing usually uses the offset printing process. This printing method uses the principle of oil-water separation to transfer the pattern to the surface of the tinplate sheet through a printing machine.

For conventional food cans and beverage packaging, the shelf life of tinplate products is usually around 3-5 years, depending on the nature of the contents. For some special-purpose tinplate products, such as chemical barrels or tool boxes, the service life can reach more than 10 years.

Why is tinplate environmentally friendly? 1. Recyclability of tinplate 2. Durability and reusability of tinplate 3. Tinplate has less environmental impact during production 4. Advantages of tinplate in reducing resource consumption

Tinplate does not have the ability to absorb ink, which means that the drying of ink depends entirely on external conditions, such as drying temperature and curing time. If the drying speed is too slow, the printed product is prone to adhesion; if it is too fast, the ink layer may be unstable, affecting the printing quality.

The unique material of tinplate determines that it must be highly compatible with ink to ensure the printing quality and durability of the pattern. The surface of tinplate is usually smooth and has a certain hardness, which makes it impossible for ordinary ink to adhere directly to its surface, and thus puts higher requirements on the performance of ink.
